Description

technical field

[0001] The invention relates to optical network configurations for transmitting optical signals. Furthermore, the invention relates to a method of monitoring optical paths of an optical network configuration. Background technique

[0002] Providers are known to lease not only specific communication equipment to customers, but even entire network configurations. These network configurations are often referred to as "dark paths" or "dark fibers" with respect to optical transmission. These optical network configurations include one or more optical paths for carrying a large number of data transmission channels available to customers. However, providers usually do not have rights to use these channels.

[0003] In order to monitor the optical path for failures or faults, one of the channels may be used for monitoring purposes. Obviously, this will reduce the bandwidth available to clients. Contents of the invention
